12 Claims. (01. 24—200)
This invention relates to strap fastenings by
which straps, such as shoulder or hose supporter
straps, belts and the like, may be adjustably se
cured to articles of clothing such as women’s
undergarments. The object of the invention is
to provide an improved strap fastening by means
of which the strap may be easily taken up or let
out.

as described above.
This operation may be un
derstood by inspection of Fig. 9.
By means of the present invention, a shoulder
strap slide fastening device has been provided
which is unusually convenient to use. For exam
ple, in bending the flexibly mounted cross bar
8 to the dotted positions in either Fig. 7 or Fig. 9,
the sides of the body of the fastening can be
grasped between the thumb and second ?nger of
the left hand, and bar 8 bent upwardly with the
first ?nger. Then with the ?ngers of the right
hand the readjustment of the shoulder strap can‘
be accomplished, after which the mere'release
of bar 8 locks the strap in readjusted position.
It will be understood that other changes than
the construction shown in the modi?cation of
Figs. 8 and 9 can be made without departing from
the invention, the scope of which is indicated in
the appended claims. Thus, for example, the ?ex-'

Ch locking bar and said other cross bar, the locking
bar being resiliently mounted on the body por
tion and normally held in a position to cause the
strap to be pressed against said other cross bar,
but being displaceable to a position in which it
does not cause the strap to be pressed against
said other cross bar, to permit ready adjustment
of the strap.

in claim 7 in which the locking bar is connected
to the body portion by a pair of flexible, resilient
arms.

9. An adjustable strap fastening comprising a
substantially rigid body portion having side mem

modi?ed to a considerable extent. Also other
